1 'o ad whom t may concern.'

Be it known thatl, JOHN R. SUNDEE, a 'citizen of 'the United States, residing at Bualo, in the county of Erie and State of New York, have invented new and useful Improvements in Spring-Lid Jewelry-Boxes, of which the following is a specification.,l

This invention relatesv to the class of boxes having a hinged lid and a spring which holds the lid either open or closed thus dispensing with a catch for retaining the lid in its closed position. i

The object of my invention is to provide such boxes with anvimproved spring of this character which vshall be simple and inexpensive in construction and which. whilel having the necessary power to reliablyclose the lid, is easy and regular in action and presents no objectionable protuberance, thus rendering ,the improvement especially desirable for jewelry boxes.

In the accompanying drawings: Figure l; is a perspective view of a jewelry box conxtaining theinvention. Fig. 2 is a vertical section thereof, showing the lid open. F ig. 3 is a similar section, showing the lid closed.-

Similar characters of reference indicate corresponding parts in the several views.

l indicates the body and 2 the hinged lid of the box, which parts are both preferably stamped of sheet metal, although they may be constructed of any other suitable material.

Located Within the box/ and seated on its bottom near its rearnwall is a horizontal slide 3 which is movable toward and from said wall and arranged in suitable guides et secured to the bottom. This slide is con-V stantly urged toward the lid-hinge by a suitable spring 5 preferably consisting of a wire bow-spring arranged crosswise of the slide and having its ends confined by lips or fastenings 6, while its intermediate portion bears against the front end of the slide.

The latter may be provided with a raised lip arm or standard 8 which bears against(y a cam or lug 9 rigidly secured to the interior of 'the rear wall of the, lid and extending downwardly and forwardly below the lid in its closed position, as shown in Fig. 3. The arm 8 is of suiiicient height to remain in engagenient with the cam in the yopen as well as the closed position of the lid, and in order to limit the openingmovement of the lid, the arm terminates n a stop or lip 10 which is encountered bv the cam, as shown in Fig. 2. To stiii'en this arm and practically prevent its deflection relative to the slide, it is provided with a longitudinal reinforcing rib or bead 11.

In the use of the box, the free end of the cam swings below :the plane of the lid-hinge or dead center when the lid is closed and above the dead center when the lid is opened. 0n closing the lid, the cam pushes the arm 8 and the slide 3 forward, straining the spring li-until the lcam passes below the dead center, when the spring'by its reaction causes said arm to force the cam toward the rear wall of the box, therebv completing the closing movement of the lid andl yieldingly holding it shut.'- spring is strained until the cani passes above the dead center, when the reacting vspring causes 'said arm to until it strikes the stop l0 of the arm, thereby yieldingly holding the lid open.

The bow spring, being comparatively long, is smooth and regular in action and yet possesses the requisite The slide and the spring are compact and occupy little space in the box, while the arm and the cam have so limited a movement that they produce no unsightly bulge of the box-lining when the improvement is .applied to a jewelrv box, for which it is more particularly designed.

I claim as my invention:

The combination of the box, its hinged lid, a slide mounted on the bottom of the box and movable toward and from the lidhinge, said slide having at its rear end a rigid upright armnovided at its upper end with a' stop,abowspring arranged in the On opening the lid, the.
